67-457: In finance , Security analysis is the evaluation and assessment of stocks or securities to determine their investment potential. It involves analyzing various factors, such as financial statements, industry trends, market conditions, and company-specific information, to make informed investment decisions. There are two primary approaches to security analysis, fundamental Analysis and technical Analysis . Security analysis deals with finding

134-423: A liability is incurred. In terms of the accounting equation , expenses reduce owners' equity . The International Accounting Standards Board defines expenses as: ...decreases in economic benefits during the accounting period in the form of outflows or depletions of assets or incurrences of liabilities that result in decreases in equity, other than those relating to distributions to equity participants. Expense

201-442: A tenant , rent is an expense. For students or parents, tuition is an expense. Buying food, clothing, furniture, or an automobile is often referred to as an expense. An expense is a cost that is "paid" or " remitted ", usually in exchange for something of value. Something that seems to cost a great deal is "expensive". Something that seems to cost little is "inexpensive". " Expenses of the table " are expenses for dining, refreshments,

268-428: A broad range of subfields exists within finance. Asset- , money- , risk- and investment management aim to maximize value and minimize volatility . Financial analysis assesses the viability, stability, and profitability of an action or entity. Some fields are multidisciplinary, such as mathematical finance , financial law , financial economics , financial engineering and financial technology . These fields are

335-812: A common definition is the one used by the United States Supreme Court decision in the case of SEC v. W. J. Howey Co. Security analysis for the purpose to state the effective value of an enterprise is typically based on the examination of fundamental business factors such as financial statements , going concern, business strategy and forecasts. Finance In these financial systems, assets are bought, sold, or traded as financial instruments , such as currencies , loans , bonds , shares , stocks , options , futures , etc. Assets can also be banked , invested , and insured to maximize value and minimize loss. In practice, risks are always present in any financial action and entities. Due to its wide scope,

402-405: A feast, etc. In accounting , expense is any specific outflow of cash or other valuable assets from a person or company to another person or company. This outflow is generally one side of a trade for products or services that have equal or better current or future value to the buyer than to the seller. Technically, an expense is an event in which a proprietary stake is diminished or exhausted, or

469-431: A high degree of computational complexity and are slow to converge to a solution on classical computers. In particular, when it comes to option pricing, there is additional complexity resulting from the need to respond to quickly changing markets. For example, in order to take advantage of inaccurately priced stock options, the computation must complete before the next change in the almost continuously changing stock market. As

536-426: A liability account, which are balance sheet accounts. An expense decreases assets or increases liabilities. Typical business expenses include salaries, utilities, depreciation of capital assets, and interest expense for loans. The purchase of a capital asset such as a building or equipment is not an expense. In a cash flow statement (flow of funds statement), expenditures are divided into three categories: Whether

603-478: A loan or other debt obligations. The main areas of personal finance are considered to be income, spending, saving, investing, and protection. The following steps, as outlined by the Financial Planning Standards Board, suggest that an individual will understand a potentially secure personal finance plan after: Corporate finance deals with the actions that managers take to increase the value of

670-710: A long-term strategic perspective regarding investment decisions that affect public entities. These long-term strategic periods typically encompass five or more years. Public finance is primarily concerned with: Central banks, such as the Federal Reserve System banks in the United States and the Bank of England in the United Kingdom , are strong players in public finance. They act as lenders of last resort as well as strong influences on monetary and credit conditions in

804-455: A new business-related asset. This cost could not be deducted in the current taxable year. However, the gas the person buys during that year to fuel that truck would be considered a deductible expense. The cost of purchasing gas does not improve or prolong the life of the truck but simply allows the truck to run. Even if something qualifies as an expense, it is not necessarily deductible. As a general rule, expenses are deductible if they relate to

871-519: A particular expenditure is classified as an expense, which is reported immediately on the business's income statement or whether it is classified as a capital expenditure (or an expenditure subject to depreciation ), which is not an expense flow of funds statement. Though, these latter types of expenditures are reported as expenses when they are depreciated by businesses that use accrual-basis accounting - as most large businesses and all C corporations do. Defining an expense as capital or income using

938-621: A personal level, expense management enables individuals to maintain a healthy financial life. By tracking and categorizing expenses, individuals gain a clear understanding of where their money is going. This awareness allows for better budgeting, saving, and investing decisions. It empowers individuals to make informed choices about their spending habits, prioritize financial goals, and avoid unnecessary debt. There are outstanding mobile applications that makes personal expense management handy, notably SMoney that are available in both iOS and Android Versions. For businesses, effective expense management

1005-551: A plethora of corporate finance and expense management apps, it is notable that Odoo and Expense.com.hk are free and simple to use. Other platforms, including Workstem and InfoTech requires an upfront payment plus relatively complex setup procedures. In both personal and corporate contexts, expense management contributes to financial stability and resilience. It helps individuals and businesses weather unexpected expenses, emergencies, or economic downturns. By establishing sound financial habits and practices, individuals can build

1072-447: A result, the finance community is always looking for ways to overcome the resulting performance issues that arise when pricing options. This has led to research that applies alternative computing techniques to finance. Most commonly used quantum financial models are quantum continuous model, quantum binomial model, multi-step quantum binomial model etc. The origin of finance can be traced to the beginning of state formation and trade during

1139-446: A sophisticated mathematical model is required, and thus overlaps several of the above. As a specialized practice area, quantitative finance comprises primarily three sub-disciplines; the underlying theory and techniques are discussed in the next section: DCF valuation formula widely applied in business and finance, since articulated in 1938 . Here, to get the value of the firm , its forecasted free cash flows are discounted to

1206-620: A taxpayer's trade or business activity or if the expense is paid or incurred in the production or collection of income from an activity that does not rise to the level of a trade or business (investment activity). Section 162(a) of the Internal Revenue Code is the deduction provision for business or trade expenses. In order to be a trade or business expense and qualify for a deduction, it must satisfy 5 elements in addition to qualifying as an expense. It must be (1) ordinary and (2) necessary ( Welch v. Helvering defines this as necessary for

1273-398: A well-diversified portfolio, achieved investment performance will, in general, largely be a function of the asset mix selected, while the individual securities are less impactful. The specific approach or philosophy will also be significant, depending on the extent to which it is complementary with the market cycle . Risk management here is discussed immediately below. A quantitative fund

1340-409: Is a term also used in sociology , in which a particular fortune or price is sacrificed voluntarily or involuntarily by something or someone to something or somebody else, often in the context that the latter is taking advantage of the former. In double-entry bookkeeping, expenses are recorded as a debit to an expense account (an income statement account) and a credit to either an asset account or

1407-482: Is about performing valuation and asset allocation today, based on the risk and uncertainty of future outcomes while appropriately incorporating the time value of money . Determining the present value of these future values, "discounting", must be at the risk-appropriate discount rate , in turn, a major focus of finance-theory. As financial theory has roots in many disciplines, including mathematics, statistics, economics, physics, and psychology, it can be considered

1474-436: Is managed using computer-based mathematical techniques (increasingly, machine learning ) instead of human judgment. The actual trading is typically automated via sophisticated algorithms . Risk management , in general, is the study of how to control risks and balance the possibility of gains; it is the process of measuring risk and then developing and implementing strategies to manage that risk. Financial risk management

1541-444: Is mathematics that is actually important in this new scenario Finance theory is heavily based on financial instrument pricing such as stock option pricing. Many of the problems facing the finance community have no known analytical solution. As a result, numerical methods and computer simulations for solving these problems have proliferated. This research area is known as computational finance . Many computational finance problems have

1608-657: Is often indirect, through a financial intermediary such as a bank , or via the purchase of notes or bonds ( corporate bonds , government bonds , or mutual bonds) in the bond market . The lender receives interest, the borrower pays a higher interest than the lender receives, and the financial intermediary earns the difference for arranging the loan. A bank aggregates the activities of many borrowers and lenders. A bank accepts deposits from lenders, on which it pays interest. The bank then lends these deposits to borrowers. Banks allow borrowers and lenders, of different sizes, to coordinate their activity. Investing typically entails

1675-497: Is referred to as "wholesale finance". Institutions here extend the products offered , with related trading, to include bespoke options , swaps , and structured products , as well as specialized financing ; this " financial engineering " is inherently mathematical , and these institutions are then the major employers of "quants" (see below ). In these institutions, risk management , regulatory capital , and compliance play major roles. As outlined, finance comprises, broadly,

1742-471: Is the branch of economics that studies the interrelation of financial variables , such as prices , interest rates and shares, as opposed to real economic variables, i.e. goods and services . It thus centers on pricing, decision making, and risk management in the financial markets , and produces many of the commonly employed financial models . ( Financial econometrics is the branch of financial economics that uses econometric techniques to parameterize

1809-485: Is the practice of protecting corporate value against financial risks , often by "hedging" exposure to these using financial instruments. The focus is particularly on credit and market risk, and in banks, through regulatory capital, includes operational risk. Financial risk management is related to corporate finance in two ways. Firstly, firm exposure to market risk is a direct result of previous capital investments and funding decisions; while credit risk arises from

1876-400: Is then often referred to as "business finance". Typically, "corporate finance" relates to the long term objective of maximizing the value of the entity's assets , its stock , and its return to shareholders , while also balancing risk and profitability . This entails three primary areas: The latter creates the link with investment banking and securities trading , as above, in that

1943-561: Is vital for maintaining financial health and achieving long-term success. By closely monitoring and controlling expenses, businesses can optimize their operational costs and improve profitability. Expense management helps identify areas of overspending, inefficiencies, or potential cost savings. It allows for strategic decision-making, such as resource allocation, investment planning, and pricing strategies. Moreover, proper expense management ensures compliance with financial regulations and enhances transparency in financial reporting. Whilst there are

2010-573: Is what had previously been the norm. An expense report is a form of document that contains all the expenses that an individual has incurred as a result of the business operation. For example, if the owner of a business travels to another location for a meeting, the cost of travel, the meals, and all other expenses that he/she has incurred may be added to the expense report. Consequently, these expenses will be considered business expenses and are tax-deductible. Many businesses benefit from automated expense reports systems for expense management . Depending on

2077-643: The Bronze Age . The earliest historical evidence of finance is dated to around 3000 BCE. Banking originated in West Asia, where temples and palaces were used as safe places for the storage of valuables. Initially, the only valuable that could be deposited was grain, but cattle and precious materials were eventually included. During the same period, the Sumerian city of Uruk in Mesopotamia supported trade by lending as well as

2144-502: The Internal Revenue Code permits the deduction of business expenses in the tax payable year in which those expenses are paid or incurred. This is in contrast to capital expenditures that are paid or incurred to acquire an asset. Expenses are costs that do not acquire, improve, or prolong the life of an asset. For example, a person who buys a new truck for a business would be making a capital expenditure because they have acquired

2211-597: The Roman Republic , interest was outlawed by the Lex Genucia reforms in 342 BCE, though the provision went largely unenforced. Under Julius Caesar , a ceiling on interest rates of 12% was set, and much later under Justinian it was lowered even further to between 4% and 8%. Expense An expense is an item requiring an outflow of money , or any form of fortune in general, to another person or group as payment for an item, service, or other category of costs . For

2278-446: The managerial application of the various finance techniques . Academics working in this area are typically based in business school finance departments, in accounting , or in management science . The tools addressed and developed relate in the main to managerial accounting and corporate finance : the former allow management to better understand, and hence act on, financial information relating to profitability and performance;

2345-724: The numerical methods applied here. Experimental finance aims to establish different market settings and environments to experimentally observe and provide a lens through which science can analyze agents' behavior and the resulting characteristics of trading flows, information diffusion, and aggregation, price setting mechanisms, and returns processes. Researchers in experimental finance can study to what extent existing financial economics theory makes valid predictions and therefore prove them, as well as attempt to discover new principles on which such theory can be extended and be applied to future financial decisions. Research may proceed by conducting trading simulations or by establishing and studying

2412-425: The proper value of individual securities (i.e., stocks, bonds and derivatives). These are usually classified into debt securities, equities , or some hybrid of the two. They can also include derivatives such as tradeable credit derivatives , commodities, futures contracts and options even if some of these are not technically securities. The definition of what is and what is not a security varies by analyst but

2479-478: The above " Fundamental theorem of asset pricing ". The subject has a close relationship with financial economics, which, as outlined, is concerned with much of the underlying theory that is involved in financial mathematics: generally, financial mathematics will derive and extend the mathematical models suggested. Computational finance is the branch of (applied) computer science that deals with problems of practical interest in finance, and especially emphasizes

2546-501: The behavior of people in artificial, competitive, market-like settings. Behavioral finance studies how the psychology of investors or managers affects financial decisions and markets and is relevant when making a decision that can impact either negatively or positively on one of their areas. With more in-depth research into behavioral finance, it is possible to bridge what actually happens in financial markets with analysis based on financial theory. Behavioral finance has grown over

2613-579: The business's credit policy and is often addressed through credit insurance and provisioning . Secondly, both disciplines share the goal of enhancing or at least preserving, the firm's economic value , and in this context overlaps also enterprise risk management , typically the domain of strategic management . Here, businesses devote much time and effort to forecasting , analytics and performance monitoring . (See ALM and treasury management .) For banks and other wholesale institutions, risk management focuses on managing, and as necessary hedging,

2680-891: The capital raised will generically comprise debt, i.e. corporate bonds , and equity , often listed shares . Re risk management within corporates, see below . Financial managers—i.e. as distinct from corporate financiers—focus more on the short term elements of profitability, cash flow, and " working capital management " ( inventory , credit and debtors ), ensuring that the firm can safely and profitably carry out its financial and operational objectives; i.e. that it: (1) can service both maturing short-term debt repayments, and scheduled long-term debt payments, and (2) has sufficient cash flow for ongoing and upcoming operational expenses . (See Financial management and Financial planning and analysis .) Public finance describes finance as related to sovereign states, sub-national entities, and related public entities or agencies. It generally encompasses

Development finance , which is related, concerns investment in economic development projects provided by a (quasi) governmental institution on a non-commercial basis; these projects would otherwise not be able to get financing . A public–private partnership is primarily used for infrastructure projects: a private sector corporate provides the financing up-front, and then draws profits from taxpayers or users. Climate finance , and

2881-672: The excess, intending to earn a fair return. Correspondingly, an entity where income is less than expenditure can raise capital usually in one of two ways: (i) by borrowing in the form of a loan (private individuals), or by selling government or corporate bonds ; (ii) by a corporation selling equity , also called stock or shares (which may take various forms: preferred stock or common stock ). The owners of both bonds and stock may be institutional investors —financial institutions such as investment banks and pension funds —or private individuals, called private investors or retail investors. (See Financial market participants .) The lending

2948-510: The field is referred to as quantitative finance and / or mathematical finance, and comprises primarily the three areas discussed. The main mathematical tools and techniques are, correspondingly: Mathematically, these separate into two analytic branches : derivatives pricing uses risk-neutral probability (or arbitrage-pricing probability), denoted by "Q"; while risk and portfolio management generally use physical (or actual or actuarial) probability, denoted by "P". These are interrelated through

3015-416: The field. Quantum finance is an interdisciplinary field, in which theories and methods developed by quantum physicists and economists are applied to solve financial problems. It represents a branch known as econophysics. Although quantum computational methods have been around for quite some time and use the basic principles of physics to better understand the ways to implement and manage cash flows, it

3082-410: The firm to the shareholders, the sources of funding and the capital structure of corporations, and the tools and analysis used to allocate financial resources. While corporate finance is in principle different from managerial finance , which studies the financial management of all firms rather than corporations alone, the concepts are applicable to the financial problems of all firms, and this area

3149-451: The first scholarly work in this area. The field is largely focused on the modeling of derivatives —with much emphasis on interest rate- and credit risk modeling —while other important areas include insurance mathematics and quantitative portfolio management . Relatedly, the techniques developed are applied to pricing and hedging a wide range of asset-backed , government , and corporate -securities. As above , in terms of practice,

3216-627: The flows of capital that take place between individuals and households ( personal finance ), governments ( public finance ), and businesses ( corporate finance ). "Finance" thus studies the process of channeling money from savers and investors to entities that need it. Savers and investors have money available which could earn interest or dividends if put to productive use. Individuals, companies and governments must obtain money from some external source, such as loans or credit, when they lack sufficient funds to run their operations. In general, an entity whose income exceeds its expenditure can lend or invest

3283-400: The foundation of business and accounting . In some cases, theories in finance can be tested using the scientific method , covered by experimental finance . The early history of finance parallels the early history of money , which is prehistoric . Ancient and medieval civilizations incorporated basic functions of finance, such as banking, trading and accounting, into their economies. In

3350-708: The fundamental risk mitigant here, investment managers will apply various hedging techniques as appropriate, these may relate to the portfolio as a whole or to individual stocks . Bond portfolios are often (instead) managed via cash flow matching or immunization , while for derivative portfolios and positions, traders use "the Greeks" to measure and then offset sensitivities. In parallel, managers — active and passive — will monitor tracking error , thereby minimizing and preempting any underperformance vs their "benchmark" . Quantitative finance—also referred to as "mathematical finance"—includes those finance activities where

3417-506: The heart of investment management is asset allocation — diversifying the exposure among these asset classes , and among individual securities within each asset class—as appropriate to the client's investment policy , in turn, a function of risk profile, investment goals, and investment horizon (see Investor profile ). Here: Overlaid is the portfolio manager's investment style —broadly, active vs passive , value vs growth , and small cap vs. large cap —and investment strategy . In

Quantum finance involves applying quantum mechanical approaches to financial theory, providing novel methods and perspectives in

3551-423: The late 19th century, the global financial system was formed. In the middle of the 20th century, finance emerged as a distinct academic discipline, separate from economics. The earliest doctoral programs in finance were established in the 1960s and 1970s. Today, finance is also widely studied through career -focused undergraduate and master's level programs. As outlined, the financial system consists of

3618-427: The latter, as above, are about optimizing the overall financial structure, including its impact on working capital. Key aspects of managerial finance thus include: The discussion, however, extends to business strategy more broadly, emphasizing alignment with the company's overall strategic objectives; and similarly incorporates the managerial perspectives of planning, directing, and controlling. Financial economics

3685-422: The management, conservation, or maintenance of property held for the production of income, or (3) in connection with the determination, collection, or refund of any tax. In investing, one controversy that mounted throughout 2002 and 2003 was whether companies should report the granting of stock options to employees as an expense on the income statement, or should not report this at all in the income statement, which

3752-420: The most common interpretation depends upon its term. When an expense is seen as a purchase, it alleviates this distinction. Soon after the purchase (that which was expenses holds no value), it is usually identified as an expense. It will be viewed as capital with life that should be amortized / depreciated and retained on the balance sheet if it retains value soon and long after the purchase. For tax purposes,

3819-444: The present using the weighted average cost of capital for the discount factor. For share valuation investors use the related dividend discount model . Financial theory is studied and developed within the disciplines of management , (financial) economics , accountancy and applied mathematics . Abstractly, finance is concerned with the investment and deployment of assets and liabilities over "space and time"; i.e., it

3886-437: The primary motive. An expense can be a loss or profit. But the loss or profit need not really be an expense. Section 212 of the Internal Revenue Code is the deduction provision for investment expenses. In addition to being an expense and satisfying elements 1-4 above, expenses are deductible as an investment activity under Section 212 of the Internal Revenue Code if they are (1) for the production or collection of income, (2) for

3953-409: The purchase of stock , either individual securities or via a mutual fund , for example. Stocks are usually sold by corporations to investors so as to raise required capital in the form of " equity financing ", as distinct from the debt financing described above. The financial intermediaries here are the investment banks . The investment banks find the initial investors and facilitate the listing of

4020-728: The rate of 20 percent per year. By 1200 BCE, cowrie shells were used as a form of money in China . The use of coins as a means of representing money began in the years between 700 and 500 BCE. Herodotus mentions the use of crude coins in Lydia around 687 BCE and, by 640 BCE, the Lydians had started to use coin money more widely and opened permanent retail shops. Shortly after, cities in Classical Greece , such as Aegina , Athens , and Corinth , started minting their own coins between 595 and 570 BCE. During

These, in turn, overlap and employ various activities and sub-disciplines—chiefly investments , risk management, and quantitative finance . Personal finance refers to the practice of budgeting to ensure enough funds are available to meet basic needs, while ensuring there is only a reasonable level of risk to lose said capital. Personal finance may involve paying for education, financing durable goods such as real estate and cars, buying insurance , investing, and saving for retirement . Personal finance may also involve paying for

4422-446: The use of interest. In Sumerian, "interest" was mas , which translates to "calf". In Greece and Egypt, the words used for interest, tokos and ms respectively, meant "to give birth". In these cultures, interest indicated a valuable increase, and seemed to consider it from the lender's point of view. The Code of Hammurabi (1792–1750 BCE) included laws governing banking operations. The Babylonians were accustomed to charging interest at
